DETAILED DESCRIPTION OF THE INVENTION Synthesis

The ortho-heterocyclicbenzenesulfonylureas of Formula I can be presented by reacting the appropriately substituted benzensulfonamide with an appropriate methyl pyrimidinyl carbamate or methyl triazinyl carbamate in the presence of an equimolar amount of trimethylaluminum according to the procedure of Equation 1. Unless indicated otherwise, all temperatures are in °C. ##STR12## where R₁, R₁₇, Q, X, Y, and Z are as previously defined.

The reaction of Equation 1 is best carried out in methylene chloride at 25° to 40° C. for 24 to 96 hours under a nitrogen atmosphere. The product can be isolated by the addition of an aqueous acetic acid solution followed by extraction of the product into methylene chloride or direct filtration of a product of low solubility. The product can ordinarily be purified by trituration with solvents such as n-butyl chloride or ether or by column chromatography.

Further details of this reaction and the preparation of the carbamates of Formula III can be found in U.S. Ser. No. 337,934 now abandoned.

Sulfonamides of Formula II may be prepared by the sequence of reactions outlined in Equation 2. ##STR13## wherein R₁ and Q are as previously defined.

The compounds of Formula V are prepared by analogy with the teaching of J. G. Lombardino in J. Org. Chem., 36, 1843.

An N-t-butyl sulfonamide of Formula IV is dissolved in an ethereal solvent, such as tetrahydrofuran, and two equivalents of n-butyllithium in hexane are added at 0°-25°. After 1-5 hours at 0°-25°, the compound of Formula V is formed. This is not isolated, but one equivalent of a copper (I) salt is added at -20° to 0°, followed by 1-1.5 equivalents of an appropriately substituted heteroaromatic iodide (VI). The reaction mixture is then heated at 40°-70° for 1-3 days, concentrated, poured onto aqueous ammonia, and filtered to provide the compound of Formula VII. The reaction of Formula 2c is conducted by heating a compound of Formula VII with 2-10 equivalents of trifluoroacetic acid or aqueous HBr with or without an inert solvent at 30°-70° for 1-3 days. The product II may be isolated as a trifluoroacetate or hydrobromide salt by evaporation of solvent and excess acid and trituration with ether. The free base may be obtained by neutralization of the salt with aqueous base, extraction into an organic solvent, and concentration of the organic extracts.

The compounds of Formula VI may be prepared according to methods known in the art, such as those reviewed in "The Chemistry of Heterocyclic Compounds," a series published by Interscience Publ., New York and London, the teachings of which are incorporated herein by reference. The iodopyridines are described in Vol. 14 of the above series, pp. 407-488. Iodopyrimidines are described by D. J. Brown and S. F. Mason in Vol. 16 of the above series. The preparation of iodopyrazines is taught by A. Hirschberg and P. E. Spoerri, J. Org. Chem., 26, 1907 (1981) and iodopyridazines are described by D. L. Aldons and R. N. Castle in Vol. 28 of the Interscience series, pp. 240-241. The iodo-1,3,5-triazines are described by E. M. Smolin and L. Rapoport, in Vol. 13 of the above series, and a method for preparing iodo-1,2,4-triazines is taught by A. Rykowski and H. C. van der Plas, in J. Org. Chem., 45, 881 (1980).

FORMULATIONS

Useful formulations of the compounds of Formula I can be prepared in conventional ways. They include dusts, granules, pellets, solutions, suspensions, emulsions, wettable powders, emulsifiable concentrates and the like. Many of these may be applied directly. Sprayable formulations can be extended in suitable media and used at spray volumes of from a few liters to several hundred liters per hectare. High strength compositions are primarily used as intermediates for further formulation. The formulations, broadly, contain about 0.1% to 99% by weight of active ingredient(s) and at least one of (a) about 0.1% to 20% surfactant(s) and (b) about 1% to 99.9% solid or liquid inert diluent(s). More specifically, they will contain these ingredients in the following approximate proportions:

Lower or higher levels of active ingredient can, of course, be present depending on the intended use and the physical properties of the compound. Higher ratios of surfactant to active ingredient are sometimes desirable, and are achieved by incorporation into the formulation or by tank mixing.

Typical solid diluents are described in Watkins, et al., "Handbook of Insecticide Dust Diluents and Carriers", 2nd Ed., Dorland Books, Caldwell, N.J., but other solids, either mined or manufactured, may be used. The more absorptive diluents are preferred for wettable powders and the denser ones for dusts. Typical liquid diluents and solvents are described in Marsden, "Solvents Guide," 2nd Ed., Interscience, New York, 1950. Solubility under 0.1% is preferred for suspension concentrates; solution concentrates are preferably stable against phase separation at 0° C. "McCutcheon's Detergents and Emulsifiers Annual", MC Publishing Corp., Ridgewood, N.J., as well as Sisely and Wood, "Encyclopedia of Surface Active Agents", Chemical Publishing Co., Inc., New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foaming, caking, corrosion, microbiological growth, etc.

The methods of making such compositions are well known. Solutions are prepared by simply mixing the ingredients. Fine solid compositions are made by blending and, usually, grinding as in a hammer or fluid energy mill. Suspensions are prepared by wet milling (see, for example, Littler, U.S. Pat. No. 3,060,084). Granules and pellets may be made by spraying the active material upon preformed granular carriers or by agglomeration techniques. See J. E. Browning, "Agglomeration", Chemical Engineering, Dec. 4, 1967, pp. 147ff. and "Perry's Chemical Engineer's Handbook", 5th Ed., McGraw-Hill, New York, 1973, pp. 8-57ff.

UTILITY

The compounds of the present invention are highly active herbicides. They can be used for broad-spectrum pre- and/or post-emergence weed control in areas where complete control of all vegetation is desired, such as around fuel storage tanks, ammunition depots, industrial storage areas, parking lots, drive-in theaters, around billboards, highway and railroad structures. Alternatively, the subject compounds are useful for plant growth modification, particularly in retarding the growth of undesired vegetation.

Rates of application for the compounds of this invention are ordinarily determined by a number of factors, including their use as either herbicides or plant growth modifiers, the types of weeds to be controlled, weather and climate, the formulation to be used, the mode of application, amount of foliage present, etc. In general terms, the subject compounds should be applied at levels of around 0.001 to 5 kg/ha, lower rates being preferred for lighter soils and/or those having a low organic matter content, for situations where only short-term persistence is required, or for plant growth modification.

The compounds of the invention may be used in combination with any other commercial herbicide, examples of which are those of the triazine, triazole, uracil, urea, amide, diphenylether, carbamate and bipyridylium types.

The herbicidal and plant growth modifying properties of the subject compounds were discovered in a number of greenhouse tests, the results of which may be seen in the following examples. ##STR24##

TEST A

Seeds of crabgrass (Digitaria, spp.), barnyardgrass (Echinochloa crusgalli), wild oats (Avena fatua), sicklepod (Cassia obtusifolia), morningglory (Ipomoea spp.), cocklebur (Xanthium pensylvanicum), sorghum, corn, soybean, sugar beet, rice, wheat, and purple nutsedge (Cyperus rotundus) tubers were planted and treated pre-emergence with the test chemicals dissolved in a non-phytotoxic solvent. At the same time, these crop and weed species, along with cotton and bush bean, were treated with a soil/foliage application. At the time of treatment, the plants ranged in height from 2 to 18 cm. Treated plants and controls were maintained in a greenhouse for sixteen days, after which all species were compared to controls and visually rated for response to treatment. The ratings, summarized in Table A, are based on a numerical scale extending from 0=no injury, to 10=complete kill. The accompanying descriptive symbols have the following meanings:

C=chlorosis/necrosis;

E=emergence inhibition;

G=growth retardation;

TEST B

Two plastic bulb pans were filled with fertilized and limed Woodstown sandy loam. One pan was planted with corn, sorghum, Kentucky bluegrass and several grass weeds. The other pan was planted with cotton, soybeans, purple nutsedge (Cyperus rotundus), and several broadleaf weeds. The following grass and broadleaf weeds were planted: crabgrass (Digitaria sanguinalis), barnyardgrass (Echinochloa crusgalli), wild oats (Avena fatua), johnsongrass (Sorghum halepense), dallisgrass (Paspalum dilatatum), giant foxtail (Setaria faberii), cheatgrass (Bromus secalinus), mustard (Brassica arvensis), cocklebur (Xanthium pensylvanicum), morningglory (Ipomoea hederacea), sicklepod (Cassia obtusifolia), teaweed (Sida spinosa), velvetleaf (Abutilon theophrastic), and jimsonweed (Datura stramonium). A 12.5 cm diameter plastic pot was also filled with prepared soil and planted with rice and wheat. Another 12.5 cm pot was planted with sugar beets. The above four containers were treated pre-emergence with one of the test compounds from within the scope of the invention.

Twenty-eight days after treatment, the plants were evaluated and visually rated for response to the chemical treatments utilizing the rating system described previously for Test A. The data are summarized in Table B.

TEST C

The test chemical, dissolved in a non-phytotoxic solvent, was applied in an overall spray to the foliage and surrounding soil of selected plant species. One day after treatment, plants were checked for rapid burn injury. Approximately fourteen days after treatment all species were visually compared to untreated controls and rated for response to treatment. The rating system was as described previously for Test A. The data are presented in Table C.

All plant species were seeded in Woodstown sandy loam soil and grown in a greenhouse. The following species were grown in soil contained in plastic pots (25 cm diameter by 13 cm deep): soybeans, cotton, alfalfa, corn, rice, wheat, sorghum, velvetleaf (Abutilon theophrasti), sesbania (Sesbania exaltata), sicklepod (Cassia obtusifolia), morningglory (Ipomoea hederacea), jimsonweed (Datura stramonium), cocklebur (Xanthium pensylvanicum), crabgrass (Digitaria spp.), nutsedge (Cyperus esculentus), barnyardgrass (Echinochloa crusgalli), giant foxtail (Setaria faberii), bindweed (Convolvulus arvensis) and wild oats (Avena fatua). The following species were grown in soil in a paper cup (12 cm diameter by 13 cm deep): sunflower, sugar beets, and rape. All plants were sprayed approximately 14 days after planting.

The results of this test demonstrate the herbicidal activity of the test compound when applied as a soil/foliage treatment. It may also be seen that the treatments retard the growth of several plant species.
